Efficiency. ICEs are 25% efficient on a good day. EVs are 80%+ efficient. A bad fuel source (coal producing electricity) with good efficiency becomes good, or at least decent, doesn't it?
Hydrogen? Horrible. 6X the CO2 of an ICE when the hydrogen is produced from natural gas, which is most hydrogen. When it's not derived from natural gas, it comes from lots of electricity + water. Where does the electricity come from? Wait for it.......COAL. |
The motor in the car is 80% efficient, sure. How efficient is the power station, the power station's fuel extraction/transportation methods, etc?
